Problems solved by technology

If the electric energy meter illegally downloads a new program without the authorization of the company on site, or the downloaded version of the program is wrong, the instability of the program will lead to information leakage or errors in important activities such as deducting fees. In the case of a large supply of electric energy meters, the loss is difficult. estimate

Embodiment Construction

[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] A method for on-site protection of an electric energy meter program, comprising the following steps:

[0020] Step 1. Embed the algorithm for calculating the license (the algorithm is the general term for the algorithm described in steps 2 to 3) into the host computer software and the energy meter program respectively, and package the algorithm into the executable software of the host computer and the energy meter respectively. Library Functions.

[0021] Step 2, the electric energy meter obtains several eigenvalues ​​related to the program compilation file. In this embodiment, the data of the 4 eigenvalues ​​relevant to the program compilation file obtained by the electric energy meter are stored in Verify_Addr (Verify_Addr is a kind of calculation CodeID required The storage location of the eigenvalue data belongs to the local variables speci...

Abstract

The invention relates to an on-site protection method for an electric energy meter program. The method comprises the following steps: 1, respectively embedding an algorithm for calculating License into upper computer software and the electric energy meter program; 2, calculating through an algorithm to obtain a CodeID; 3, enabling the upper computer software to calculate to obtain a fixed-length byte License through an algorithm according to the CodeID; 4, downloading the obtained License into a License structural body in the electric energy meter, and recompiling an electric energy meter program; 5, downloading the successfully compiled program into a table for running; And 6, after the electric energy meter runs, calling a verification module in the library function to judge the legalityof the electric energy meter, if the electric energy meter is legal, normally running, and if the electric energy meter is illegal, stopping running after valid time. The program running legality ofthe electric energy meter can be enhanced, the program issuing legality is guaranteed, it is guaranteed that the electric energy meter can respond in time after the program is tampered, metering or fee deduction errors are avoided, and then the stability of the electric energy meter is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric energy meter management in electric power systems, and in particular relates to an on-site protection method for electric energy meter programs. Background technique [0002] With the official implementation of the State Grid Corporation of China's smart energy meter series standards, the functions of the energy meter have increased significantly, and more and more important information such as remaining electricity charges and electricity prices have been involved. As a device that does not allow on-site software upgrades, the program's Whether it is legal or not is an important factor to ensure the normal operation of the energy meter. If the electric energy meter illegally downloads a new program without the authorization of the company on site, or the downloaded version of the program is wrong, the instability of the program will lead to information leakage or mistakes in important activities...
